Not a technical freebie, but customers of Princess Auto on Saturday the 21st will get a free can of WD-40 with any purchase. Princess Auto have loads of random stuff to buy, things you wouldn’t always expect, so I occasionally drop by to see whats on offer, and perhaps on the 21st you should too.
The free can of WD-40 is the 85 gram size. Only one can per customer (no claiming it 20 times) and it will run while supplies last. It’s funny as the company also have a sidewalk sale on the 21st so you can even get sale items and pick up your free can.
